=item &get_sequence_assessment_data()

Use lonnavmaps to build a data structure describing the order and
assessment contents of each sequence in the current course.

The returned structure is a hash reference.

{ title => 'title',
symb => 'symb',
src => '/s/o/u/r/c/e',
type => (container\|assessment),
num_assess => 2, # only for container
parts => [11,13,15], # only for assessment
response_ids => [12,14,16], # only for assessment
contents => [........] # only for container
}

$hash->{'contents'} is a reference to an array of hashes of the same structure.

Also returned are array references to the sequences and assessments contained
in the course.
